Abstract
Ostomy wafers, ostomy devices incorporating ostomy wafers, and methods of applying ostomy wafers and ostomy devices are disclosed herein. An ostomy wafer may include an external layer and a convex surface coupled to the external layer. An ostomy device may include an ostomy pouch and an ostomy wafer coupled to the ostomy pouch that includes an external layer and a convex surface coupled to the external layer.
Claims20
An ostomy wafer comprising:
- an external layer having an opening to permit the passage of effluent therethrough and a first adhesive to adhere to external skin around a stoma of an ostomate;
- a convex layer coupled to the external layer that includes a stoma channel sized to at least partially receive the stoma, at least one groove radially spaced from the stoma channel that extends at least partially through the convex layer to facilitate deformation of the convex layer complementary to a shape of the stoma, and a second adhesive to further adhere to the ostomate,
- wherein:
- the at least one groove includes a plurality of grooves spaced circumferentially from one another about the convex layer, and
- at least two of the plurality of grooves extend through the convex layer to different depths.

An ostomy wafer comprising:
- an external layer having an opening to permit the passage of effluent therethrough and a first adhesive to adhere to external skin around a stoma of an ostomate;
- a convex layer coupled to the external layer that includes a stoma channel sized to at least partially receive the stoma, at least one groove radially spaced from the stoma channel that extends at least partially through the convex layer to facilitate deformation of the convex layer complementary to a shape of the stoma, and a second adhesive to further adhere to the ostomate,
- wherein:
- the stoma channel includes a built-in structure, and
- the built-in structure is located interiorly of an internal surface of the convex layer that defines the stoma channel.

An ostomy wafer comprising:
- an external layer having an opening to permit the passage of effluent therethrough and a first adhesive to adhere to external skin around a stoma of an ostomate;
- a convex layer coupled to the external layer that includes a stoma channel sized to at least partially receive the stoma, a plurality of grooves radially spaced from the stoma channel that extend at least partially through the convex layer to facilitate deformation of the convex layer complementary to a shape of the stoma, and a second adhesive to further adhere to the ostomate,
- wherein at least one of the plurality of grooves extends through the convex layer to a depth that is equal to an entire height of the convex layer.
